Purchased our Panasonic SC-HT75 unit in 2002 - had nothing but problems back & forth to repairers - now we have F61 error... It plays for a while, then switches itself off with a F61 error, or we may have had the system turned off for a while, turn it on to play a DVD or radio and get an F61 error. We have switched the unit off, turned off at powerpoint for extended periods of time - all with same result. Would love to hear if anyone has a solution...

You have a problem with speaker cords:-1-make marks with tape or any marker pen in all speaker cords(left-right-sub- front-rear).2-after marking remove all speaker cords.3-insert them one by one until f61 appear.4-the cord that connected and make the trouble is bad please change it with new one.

Hi, F61
is and amp error code. probably needs an output ic. could be a
shorted speaker or bad cooling fan. Disconnect all speakers and turn it
on. if the fans run and it still displays f61 then odds are very good
an amp ic is bad.'''Hope it helped.

People say that it is a fan problem - when it gets stuck with dust or does not work properly the system recognizes it and gets blocked in order to prevent overheating of the components. I changed the fan but the problem with F61 presists despite people say that changing the fan would solve the problem.

F 61 error means the failure of FAN
most probably dust in the fan made it to stop working so clean the dust
and connect the fan to an external supply of 12v(using red and black
wire) for 5 minutes and reconnect it to the unit otherwise replace the
fan with new one.
Surely this will solve the problem.

The F61 indicates a problem detected in the output amp stage and the unit us shutdown to prevent further damage. If you can supply the model number, I can give you the part required and the approximate cost.
